ADR3630BRMZ-R7

Overview

The ADR3630BRMZ-R7 is a precision micropower voltage reference from Analog Devices, delivering a nominal 3.0 V output in an 8-lead MSOP package. It features a maximum temperature coefficient of 3 ppm/°C and an initial accuracy of ±0.04%. The device supports up to 70 mA sourcing and 20 mA sinking current with low dropout characteristics. Operating over a -40°C to +125°C range, it includes shutdown functionality and DigiTrim calibration for long-term stability.

Feature Summary

• High precision performance utilizing proprietary DigiTrim technology for calibrated output voltage and temperature coefficient.
• Capable of replacing standard LDO regulators due to high current drive capacity and low quiescent power consumption.
• Features low thermal hysteresis and minimal long-term drift to ensure extended system lifetime accuracy.

Applications

• Precision power supplies
• Portable instrumentation
• Process transmitters
• Remote sensors
• Medical instrumentation

Procurement Notes

Verify the specific B-grade suffix and reel packaging designation when ordering. Confirm that the required load capacitance meets the minimum specification for stable operation. Ensure input voltage limits are respected within the design parameters. Check for any regional distribution restrictions or limited availability status before finalizing procurement plans.

Selection Notes

Select this component for applications requiring high current drive capability alongside precision voltage referencing. The B-grade specification ensures tighter tolerance bounds compared to lower grades. Consider the 8-lead MSOP footprint for space-constrained designs. Evaluate thermal dissipation requirements if operating near maximum current loads at elevated temperatures.

Part Context

This part belongs to the ADR36xx series of micropower voltage references. It shares architectural similarities with the ADR3625 and ADR3650 models, differing primarily in output voltage and specific grading. The series is designed to offer superior performance over traditional bandgap references while maintaining low power consumption.
